@replit/ruspty v3.4.0

@replit/ruspty - PTY for JavaScript through Rust FFI

A very thin wrapper around PTYs and processes.

const { Pty } = require('@replit/ruspty');

const pty = new Pty({
  command: '/bin/sh',
  args: [],
  envs: {},
  size: { rows: 24, cols: 80 },
  onExit: (...result) => {
    // TODO: Handle process exit.
  },
});

const read = pty.read;
const write = pty.write;

read.on('data', (chunk) => {
  // TODO: Handle data.
});
write.write('echo hello\n');

The biggest difference from existing PTY libraries is that this one works with Bun, and doesn't cross the FFI bridge for every input/output instead requiring the consumer to deal with the fd of the PTY.
